With Yaathisai, the upcoming film about Pandiyas, all set to hit theatres on April 21, the makers are promoting the film in full swing. On Sunday, director Karthik Subbaraj praised Dharani Rasendran, the director of Yaathisai, on Twitter. 

Sharing the film's trailer, Karthik Subbaraj wrote, "Stunning trailer. Amazing work by the director Dharani Rasendran & team. Looking forward for the film, Yaathisai." (sic)

The trailer of Yaathisai revealed that the film is a periodical fiction based on the 7th-century Pandiyan prince Ranadheera Pandiyan. He ruled during a time when the Chola dynasty lost its power, and its people were forced to live in the woods. The film will also focus on the revolt of Eyinars and Cholas against Pandiyas, and how the war affected the lives of Devaradiyars.

Yaathisai is backed by Venus Infotainment and Six Star Entertainment. The film stars Shakthi Mithran, Seyon, Rajalakshmi, and Guru Somasundram, among others. The film's technical crew includes cinematographer Akilesh Kathamuthu, editor Mahendran Ganesan, music composer Chakravarthy and art director Ranjith Kumar.
